Glass strategy: Hanford’s enhanced waste glass program
The mission of the Department of Energy’s Office of River Protection (ORP) is to complete the safe cleanup of waste resulting from decades of nuclear weapons development. One of the most technologically challenging responsibilities is the safe disposition of approximately 56 million gallons of radioactive waste historically stored in 177 tanks at the Hanford Site in Washington state.
ORP has a clear incentive to reduce the overall mission duration and cost. One pathway is to develop and deploy innovative technical solutions that can advance baseline flow sheets toward higher efficiency operations while reducing identified risks without compromising safety. Vitrification is the baseline process that will convert both high-level and low-level radioactive waste at Hanford into a stable glass waste form for long-term storage and disposal.
Although vitrification is a mature technology, there are key areas where technology can further reduce operational risks, advance baseline processes to maximize waste throughput, and provide the underpinning to enhance operational flexibility; all steps in reducing mission duration and cost.

One of the challenging problems of magnetized target fusion (MTF) is developing ways to transport energy to the target situated at a distance far enough from the energy source so as to prevent damage to the permanent parts of the source. Several schemes were considered in the past, including the use of particle beams coupled with the inverse diode, mechanical projectiles in combination with magnetocompressional generators, and the plasma liner. In this paper, a possible modification of the original concept of the plasma liner (by Thio et al.) is described. The modification consists of creating a thin, higher-density shell made of a high-Z plasma and accelerating it onto an MTF target by the thermal pressure of hydrogen plasma with a temperature of ~10 eV. We discuss constraints on the parameters of this system and evaluate the convergence ratio that can be expected.
